Application filed. January 5, 1904. Serial No. 187.841.

T0 rrZZ whom it may concern.-

Be it known that I, AUeUs'rUs D. KLABER, a subject of the King of Great Britain, residing at London, England, have invented acertain new and useful Improvement in Printing- 'Machines, of which the following is a description.

The object of the presentinvention is to provide a printing-machine supplied with means of a simple but effective character for preventing offsetting upon the sheets printed therein. In carryingout the invention I employ in connection with such a printing-machine a mechanism for collecting the printed sheets as they are fed from such machine upon a band or webbing, preferably of absorbent paper or other material, suitably mounted as, for instance, upon rolls or drums and fed from oneroll or drum to the other.

such band or webbing, but also dried on blotted thereon and subsequently delivered in any suitable manner.

Although applicable to printing-machines generally, the invention has been designed particularly for stencil-printing or' duplicat- -ing apparatus and will be described herein as an adjunct of such a device.

In the drawings, Figure 1 is a side eleva-v tion, and Fig. 2 an end elevation, of a stencilduplicating machine, such as the rotary neostyle, provided with my invention.

suitable gearing or other connection,toa pulley a, the purpose of which will be presently described.

D designates a rollframe, here shown as mounted upon a plate cl, pivoted, by means of Such printed sheets are not only collected upon the rod cZ,in a sleeve d upon the shelf (Learried by the brackets b.

In conjunction with the mechanism just described a locking device is employed, here shown as a spring-pressed bolt E, actuatedby the lever the upper end of said bolt projecting through a perforation in the shelf O, through the board 0 on said shelf, and into one or the other of the perforations 0, formed in the plate cl. WVhen the locking device is in engaging position, (in which it is shown in Fig. 2,) the roll-frame D is rigidly secured in one or the other of its two positions hereinafter described.

F designats a roll mounted upon a shaftf in the side members of the frame D. Outside said frame this shaft is provided on one side with the wheel f, keyed or otherwise secured thereto and with which coacts a spring-brake f here shown as carried by the stand 'or table upon which the apparatus is mounted.

The other end of said shaft f, also, outside the frame D, is provided with a pulley f and a wheel f, the latter being outsidethe former and both beingloosely mounted on said shaft. If desired, I may also employ in connection with the wheel f a spring-brake f, similar to the brake f and also carried by the stand upon which the mechanism is mounted.

G designates a friction-pulley, here shown as mounted upon a shaft g, supported by bracket 9 and carrying belt-pulley g coacting, by means of belt g, with the pulley a, driven from the drum of the neostyle or other duplicating apparatus.

H designates a roll similar to the roll F and also mounted within the frame D upon a shaft it. One end of this shaft outside said frame D is provided with a pulley It, engaging with the pulley f mounted on the shaft f.

I designates a band or webbing carried upon one of the rolls F H and fed therefrom to the other.

J designates the feed-tray, and K the delivery-board, of the duplicating-machine.

L designates a, supplementary deliveryboard, here shown as mounted upon rods or wires Z, the lower ends whereof are secured to the shelf C.

M designates a guard, here shown as supported by rods or wires m, carried also by the shelf C.

The operation of the apparatus is as follows: Motion imparted to the drum A of the stencilprinting device is transmitted to the pulley (0 and thence to the pulley g and friction-pulley Gr. The wheel f* and pulley f being attached, the rotary movement is, through these wheels, transmitted to the pulley it of the lower roll H. The roll F has therefore only such motion as is imparted to it as the roll H draws the band or web I therefrom, and the coaction of the brake f with the wheel f on the shaft of said roll F prevents said roll from overrunning. The sheets to be printed are fed over the feed-tray J and after being printed upon by the stencil on the periphery of the drum of the duplicating-machine are passed out over the delivery board or chute K- and over the supplementary delivery-board L to the surface of the roll H and between such surface and the band or web I, being taken up thereon. Consequently the successive sheets are wrapped upon said roll H as the movement progresses and kept out of contact, as each is covered successively by successive portions of said band or web. After the operation just described has continued sufficiently long totransfer all of the band or web I from the roll F to the roll H said rolls and the frame in which they are mounted may be reversed (being released for such reversal by the locking device E, above described) and the operation continued, the sheets already printed upon and carried upon the roll H being delivered therefrom properly blotted or dried, and simultaneously the printing continued, the subsequent sheets being collected upon the opposite side of the band or web I. Upon such reversal the friction-pulley G will coact with the wheelf", whereby the roll F will be driven, as well as the roll H, the movement of the latter being in this case dependent upon the pull of the web or band I from this roll to the roll F. Said band or web now being made to travel in the opposite direction 2 6., from the roll H to the roll Fthe printed sheets fed over the supplementary delivery-board L will be carried by the band I and collected upon the roll F. Simultaneously the printed sheets formerly collected upon the roll H will be released therefrom and delivered upon the delivery-board N, being prevented from displacement by the guard M.

It is obvious that any number of copies may be printed, collected, dried, and delivered in the manner hereinbefore described, this number being independent of the length of the band or web I, since after this has been utilized from one end to the other the frame containing the rolls on which such web or band is mounted may be reversed and the operation continued as before. It will also be obvious that the apparatus herein described may be modified in many respects without departing from the spirit of the invention---as, for instance, by the employment of gearing rather than frictional contact for the driving of the various parts, &c.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a printing-machine, the combination with printing mechanism, of two reversible rolls arranged in juxtaposition thereto and a band or web carried thereby, mechanism for transmitting motion to said rolls and :leeding said band or web from one to the other and means for delivering sheets to said band or web to be wrapped between the same and the roll or core on which it is wound, substantially as set forth.

2.
